Joke about rich brothers

Three rich brothers wanted to do something special for their old mother. She had her birthday. The first brother bought her a big house. The second brother gave her a big car, with a driver. The third brother remembered that his mother loved to read, but she had bad eyes. So he gave her a special parrot. This parrot could read books.

Soon, the brothers got letters from their mother. The first letter said, "The house is very big. I only live in one room, but I must clean all house."

The second son got a letter, "I don’t go out very often. I don’t need the car and the driver is a bad man."

The third son got a letter, "My sweet boy, you know what your mother loves. The chicken was very tasty."
